Serial Protocol Descriptions
Model 200 Compatible Protocol
Performer may be used as a Model 200 Production Switcher
peripheral. This protocol allows Performer to accommodate the
LEARN and RECALL commands of the Model 200 dialect.
Registers within Performer are capable of storing the
configuration of the Performer matrix in each of 64 locations.
Thus, Performer may be set up in a unique configuration as part
of an Model 200 (E-MEM) routine, the configuration “learned”
and stored by Performer, then recalled quickly when correctly
addressed by the Model 200.
A command line consists of Hex ASCII (0-F) and upper case
alphabetic ASCII (A-Z) characters in the following format:
Alphabetic character identifying the command.
L = Learn command. R = Recall command.
6 Hex characters identifying which peripherals are
to learn the data to follow. The peripheral number
corresponds to the Performer address (Switch S2).
3 Hex characters identifying which register number
to store/recall a router configuration in/from.
Carriage Return.
Ignoring the trailing return, each command has exactly 10
characters.
Each command must end with a carriage return (which executes
the command and starts a new command line).
The bit corresponding to Performer address must be
set or Performer will ignore the command.
To use the Learn command, Performer is manually set up in a
desired configuration before the Learn is executed. The current
configuration will be stored in the designated register.
The Recall command simply recalls the learned configuration
from the specified register and switches Performer accordingly.
